Genetic and physiological aspects of growth, body composition and feed efficiency in mice: a review     

R C Malik 《Journal of animal science》1984,58(3):577-590

A review is presented of the genetic and physiological aspects of growth, body composition and feed efficiency in mice. The genetic parameters considered are: nature and extent of within and between-line genetic variation for body weight and growth rate; direct and correlated responses to selection for body weight, weight gain, feed intake and feed efficiency; direct genetic effects of the offspring (gO); maternal genetic effects (gM); heterosis in the offspring (hO); maternal heterosis (hM), and recombination effects in the offspring (rO). The physiological parameters considered are energy requirements for maintenance and growth. The role of thermoregulatory thermogenesis in relation to the partitioning of metabolizable energy between maintenance and growth requirements of large and small mice is emphasized. The relationship of feed efficiency with other traits is reviewed at length.  相似文献

Humoral and Delayed-type Hypersensitive Responses againstListeria monocytogenes Phosphatidylinositol-specific Phospholipase C in Experimentally Infected Buffaloes     

Chaudhari SP  Malik SV  Barbuddhe SB 《Veterinary research communications》2004,28(7):569-579

The kinetics of antibody production against phosphatidylinositol-specific phospholipase C (PI-PLC) and the isolation pattern of Listeria monocytogenes from bacteriological samples were studied following oral infection of buffalo calves with 3 x 10(9) cells each of pathogenic L. monocytogenes. Antibodies to PI-PLC appeared by 4-8 days post infection (PI), with a peak between days 7 and 16 PI, when tested by indirect plate-ELISA. Subsequently, antibody titres in all the animals declined and became undetectable on days 26-35 PI onwards until the study concluded on day 211 PI. Dot-ELISA could detect the antibodies to PI-PLC 1-2 days earlier and at higher titres as compared to plate-ELISA. L. monocytogenes could be recovered from faeces, nasal swabs and haemocultures from days 2 to 33, days 2 to 21 and days 11 to 17 PI, respectively. Antibodies to PI-PLC were detected during the course of active infection but their titres declined sharply once animals became culturally negative. Sonicated antigen elicited the highest delayed-type hypersensitivity response, followed by PI-PLC and listeriolysin O.  相似文献   

Infections of the subcutis and skin of dogs caused by rapidly growing mycobacteria     

Malik R  Shaw SE  Griffin C  Stanley B  Burrows AK  Bryden SL  Titmarsh J  Stutsel MJ  Carter SA  Warner A  Martin P  Wigney DI  Gilpin C 《The Journal of small animal practice》2004,45(10):485-494

Nine dogs with panniculitis due to rapidly growing mycobacteria (RGM) were examined over 17 years. Dogs were two to 15 years; five were male, four were female. All were obese or in good condition. Antecedent injury, typically a dog bite or vehicular trauma, could be identified in some patients, while one bitch had hyperadrenocorticism. Infections involved different locations, although the cervicothoracic region, dorsum or flank were most often affected. Patients were systemically well, apart from one dog with pyrexia and two with pain or lameness. Cytology demonstrated pyogranulomatous inflammation, but in only one case was it possible to see acid-fast bacilli (AFB) in smears. Histology demonstrated chronic active pyogranulomatous panniculitis and dermatitis; AFB could be detected in only four specimens. Culture of aspirates or resected tissues demonstrated RGM in all cases, comprising six Mycobacterium smegmatis group and three Mycobacterium fortuitum group isolates. Resection of infected tissues, perioperative injectable antimicrobials and long courses of oral antimicrobials chosen according to susceptibility data generally effected a cure, although some cases recurred.  相似文献   

Isolation of pathogenic Listeria monocytogenes and detection of antibodies against phosphatidylinositol-specific phospholipase C in buffaloes     

Chaudhari SP  Malik SV  Chatlod LR  Barbuddhe SB 《Comparative immunology, microbiology and infectious diseases》2004,27(2):141-148

The isolation of pathogenic Listeria spp. in bacteriological samples, and anti-phosphatidylinositol-specific phospholipase C (anti-PIPLC) antibodies in sera of buffaloes were studied. Isolation of the pathogen was attempted from the samples by selective enrichment in University of Vermont Medium and plating onto Dominguez-Rodriguez isolation agar. Pathogenicity of the isolates was tested by Christie, Atkins, Munch Petersen test and mice incoulation test. Listeria spp. and L. monocytogenes were isolated from 8.8 and 2.4%, and 4.8 and 1.6% of 125 each meat and blood samples, respectively. Out of the 125 samples each of feacal, nasal and vaginal swabs from buffaloes 8 and 4%, 13.6 and 2.4%, and 6.4 and 2.4% were positive for Listeria spp. and L. monocytogenes, respectively. L. ivanovii was confirmed from 0.8% vaginal sample. A total of 125 serum samples were tested by phosphatidylinositol-specific phospholipase C (PIPLC) based indirect ELISA of which 4.0% turned out to be seropositive.  相似文献   

Antigenic differences between H5N1 human influenza viruses isolated in 1997 and 2003   总被引：5，自引：0，他引：5  

Horimoto T  Fukuda N  Iwatsuki-Horimoto K  Guan Y  Lim W  Peiris M  Sugii S  Odagiri T  Tashiro M  Kawaoka Y 《The Journal of veterinary medical science / the Japanese Society of Veterinary Science》2004,66(3):303-305

To assess whether the antigenic properties of H5 hemagglutinin (HA) change over time due to antigenic drift, we produced a panel of monoclonal antibodies (mAbs) against the HA of the index H5N1 human influenza A virus, A/Hong Kong/156/97. By immunizing mice with a plasmid expressing this HA and boosting the initial immunization with cell lysates transfected with the plasmid, a total of six hybridomas producing HA-specific mAbs were established: four to the HA1 subunit with hemadsorption-inhibiting activity and two to the HA2 subunit. None of the mAbs to HA1 could bind to the HA of a recent human isolate, A/Hong Kong/213/2003, indicating that there are substantial antigenic differences between the H5N1 human influenza virus isolated in 1997 and that isolated in 2003.  相似文献   

The use of real-time PCR in the diagnosis and monitoring of Mycoplasma haemofelis copy number in a naturally infected cat   总被引：1，自引：0，他引：1  

Braddock JA  Tasker S  Malik R 《Journal of Feline Medicine and Surgery》2004,6(3):161-165

A 5-year-old male neutered cat was diagnosed with severe anaemia due to acute Mycoplasma haemofelis infection. Inflammatory respiratory disease was present concurrently. The cat was treated successfully using a fresh transfusion of whole blood and a 6 week course of doxycycline. The patient made a rapid recovery although the allergic airway disease subsequently required specific therapy consisting of inhaled fluticasone and salbutamol. Real-time quantitative PCR assays confirmed the presence of M. haemofelis DNA copies in the blood at presentation. Repeat PCR assays showed a reduction in copy number during treatment and negative PCR results were obtained both 91 and 425 days after presentation. The report describes, for the first time, the use of real-time PCR in the diagnosis and monitoring of natural M. haemofelis copy number, as well as the induction of long-term negative PCR status.  相似文献   

Concurrent Fusarium chlamydosporum and Microsphaeropsis arundinis infections in a cat     

Kluger EK  Della Torre PK  Martin P  Krockenberger MB  Malik R 《Journal of Feline Medicine and Surgery》2004,6(4):271-277

A 7-year-old cat was presented initially with multiple draining sinuses on the metatarsal region of its right hindlimb. Another lesion had appeared at the same time on the fifth proximal interphalangeal joint of the left forelimb. Histopathological examination of a biopsy from the right hindlimb lesion revealed chronic pyogranulomatous inflammation associated with yeast-like bodies and septate mycelia; a fungus was cultured on conventional media but not identified further. Culture of a swab collected from the left forelimb lesion demonstrated a pigmented fungus, also not characterised further. Although there was initially a favourable response to ketoconazole (Nizoral, Janssen-Cilag Pty. Ltd) and beta-lactam therapy, the infection in the hind limb relapsed subsequently, and Fusarium chlamydosporum was cultured from deep biopsy specimens. Clinical improvement followed debridement and itraconazole (Sporanox, Janssen-Cilag Pty. Ltd; 100 mg orally once daily), however amputation of the limb represented the best chance for a cure. The cat made an uncomplicated recovery following surgery and remained well for five months until the lesion on the left forelimb recurred. Amputation of the distal fourth digit was then performed, and the resected tissue submitted for culture. The dematiaceous fungus Microsphaeropsis arundinis was subsequently cultured. The cat remained well for several months, until a further F. chlamydosporum infection developed on the body wall. This was excised 7 months ago, and no lesions have recurred in this area. Importantly, this is the first reported case of M. arundinis infection in a mammalian host.  相似文献
